FKB/GNDRAD/M1 - Reprocessed: Incorrect calibrations

An incorrect calibration coefficient was applied to the up_short_hemispheric instrument 
(PSP) for the specified time period.  Changes in the ARM PSP calibration procedure now 
generates two different calibration coefficients for the same instrument, Cf(non "IR 
corrected")and Cfc("IR corrected").  CFc should have been applied to this instrument but CF was 
erroneously used.

The affected PSP is S/N 34292F3 Cf=117.61 (incorrect applied), Cfc(correct)=116.07W/m2/mV

These data were reprocessed and archived in March 2008.

FKB/ECOR/M1 - Flux Data Suspect For Some Wind Directions

For some wind directions the horizontal fetch was not representative of the field in which 
the AMF was located.  Therefore, for the wind direction ranges 
40-159 and 176-209 degrees, the fluxes are affected by insufficient fetch and  surfaces, 
buildings, and vegetation that are not similar to the local field conditions.

• latent heat flux(lv_e)
• CO2 flux(fc)

FKB/MET/M1 - Reprocess: ORG Data has very small rainrate values

The ORG data is collected via analog signal and not digital.  Therefore, we
   continuously collect data even when no rain is occurring.  We also capture
   small events such as leaves, large bugs, dust, etc blowing through the
   measurement path.  Because this discrete event occurs quickly the value is
   usually captured for 1 or 2 seconds.  This value is then averaged to the
   minute producing rainrate on the order of .009 mm/hr or less.  These values
   are not indicative of rain and should be removed from the record or summing
   over long periods can bias the climate record.  We are reprocessing the data
   to remove these small values and are adjusting the collection program to
   remove them before ingest.

FKB/MET/M1 - Wind Speed data contain offset due to induced voltage

The marine model of the RM Young wind sensor needs twisted pair shielded cable.  The 
manufacturer did not originally supply the pigtail with twisted pair shielded cable.  Use of 
twisted pair shielded cable for the rest of the cable run to the logger was also not 
specified.  This caused an induced voltage in the wind speed line from the wind direction 
excitation.  The induced voltage varied from sensor to sensor and probably changed anytime 
the cable was replaced or parts of the wind sensor were repaired or replaced. The induced 
voltage has been seen to vary from 0.15 m/s to as much as 1.08 m/s.
